Promoting crop diversification in European agriculture

A major 5-year European project ˗ DiverIMPACTS launched

Using legume-based mixtures to enhance the nitrogen use efficiency and economic viability of cropping systems.

Acronym:

LegLINK

Contract period:

1 December 2009 to 29 February 2012

Main funder:

Defra

Contact staff at ORC:

Robbie Girling

Other staff involved:

Thomas Döring

Project aims

The overall aim of the project is to improve nitrogen use efficiency in UK arable systems. It aims to create a legume based mixture (LBM) that can have significantly improved resilience in fertility building and nitrogen release dynamics compared to the traditional grass/clover mixtures, over a range of environmental conditions.

By studying the growth parameters of individual legume species, and grasses in field trials, and the mixture of all trial species (the all species mixture - ASM) in participatory trials, we will better understand the potential, and the mechanisms by which a designed LBM may increase the profitability of UK arable systems, and have robust data on which to base the development of commercial seed mixes.

ORC's role

ORC is leading the project and conducting field trials on its field site in Suffolk (Wakelyns Agroforestry) and on an additional site (Barrington Park, Gloucestershire).
